ADJUSTABLE SCREEN.

Application led July 18, 1923, Serial No. 651,695.

1To all whom t muy concern:

Be it known that I, CASPER HUGO GRINGS, a` citizen of the United Statesof America, and a resident of .llVaterloo, Blackhawk County, Iowa, haveinvented certainv new and useful Improvements in Adjustable Screens, ofwhich the following isa speciiication.

`My invention relates to improvements in adjustable screens, and theobject of my improvement` is to supply for wall apertures includingwindows havingmovalole sashes, a flexible screen element, which may ormay not beof reticulated material, and cooperating holding andsupporting elements for keeping the screen in a proper .positioncovering such an aperture, the screen coacting with the said elementsinsuch a` manner as to be adjustable therein in the direction of itslength.

I `have accomplished this object by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, it being understood that changes in the precise embodiment ofinvention herein disclosed can be made within the scope of what isclaimed without departing from t-he spirit of the invention.

In saiddrawings, Fig. l is an elevation of the inner face of a sashedwindow, showing the lower sash partially elevated and my imw provedadjustable screen mounted within the casing to close the opening beneathsaid sash. Fig. 2` is an elevation of the screen member only as unrolledbefore adjustable mounting thereof in a window casing. Fig. 3 is a-topedge view of the screen member showing its tubular stile receiving endsplaced in appropriate positions relative to the main body of the screenfor conveniently mounting these tubular ends in grooved holding devicesmounted on the opposite jambs of saidv casing. Fig. 4. is a horizontalsection on` a larger scale of a window casing and ofthe lower sash therin, showing my improved screen mounted across the casing, parts beingbroken away.

Fig. 5 YVand Fig. 6 are respectively enlarged perspective views oftheupper and lower clips of the device. Figs.'7 -and- 8 are perspectiveviews of the upper ends of the .screenholders showing the rolled endsofthe iiexible screen member mounted in the grooves thereof. Fig. 9 is anenlarged perspective view of the fastener used to secure the upperlongitudinal edge of the screen member under and to a finger-lift on thelower sash. Fig. l() is a top plan view of the said fastener in usesecuring said screen to said finger-lift- Fig. ll is a horizontalsection of an end stile and of the holding element therefor.

It is well known that even in the same building or other structurewindow openings often vary in width, so that it is desirable that ascreen member to properly cross and lit any of the openings should beadjustably adaptable theretoand then supported under propertension insuch a manner that it will closely contact with the adjacent structuresto prevent ingress or egress of air otherwise than under the conditions.for which the screen is designed.

lith this end in View, I supply aflexible screen sheet l, which may beimpervious to air if desired, or may be made of reticulated material topermit a gentle transpiration through its substance.` The horizontallongitudinal margins l5 and 16 are turned over tubularly and hemmed, asare also ,the opposite end margins at 18 and 19. As shown in Fig. 2, ashort vertical slit may be made in the lower tubular part 16 at 38 topermit either the introduction or the removal of a metal rod 17 whichthus serves as an` elongated weight to keep the lower margin of thescreen l straight as also drawn down to contact closely with the sillmember 32 underneath.

llhen the rod 33 has been removed the" screen may, together Vwith `Hatsticks or stiles 14; in the end tubes 1S and 19, be rolled up to occupybut little space.

I supply the following described holding devices for the ends of saidscreen; leftshand device shown in Figs. l and 7 `is an elongatedvertically disposed plate 0f metal 2 having one vertical margin bent toone side at a right angle at 4, the outer edge of which is notched at 5for the adjust-4 able placing of screws 6 `to secure the holder to thejamb 31 with the body 2 closely abutting' the inner face of the lowersash 28 cross-bar when the sash is raised. This holder Q. has itsright-hand margin curvilin- The early bent over to the same side to forma groove or channel at 3. The body 2 has holes as at 7 to receivepivot-screws 34 on which spring-clips 8 and 8 having registering holes13 are pivotally mounted.

The right-hand holder 2O has its inner margin ciirvilin early grooved ortroughed at 23 toward the window to abut closely upon the sash, theholder being bent slopingly at 21 toward the outwardly directed marginalpart 22 to thus mount the holder in position.

The ends of the screen 1, as shown in Fig. 3 maybe bent around inopposite' directions loopwise with their st-iles 14 so as to permit thetubes 18 and 19 with said stiles to be respectively slipped endwisedoiiiiwardly into the holder grooves or inturned margins 3 and 23 afterthe screen in case of need has had its ends rolled one or more timesaround the stiles to effect the proper longitudinal tension in thescreen. This disposition ot' the rolled extremities of the screen isbest illustrated in said Figs. 7 and S. Vhen the screenhas been thusflatly stretched and end-seciired in said holders, additional tensionvmay be made therein to take up any residual slack by means of the saidspringclips 8 and 8 These clips are alike, except that'the upper clip 8has its :tree terminal bent away from the screen at 9. Each clip l isbent toward the holder 2 in an offset at 10. and 11, to override thebent margin 3 with sufficient clearance, when swiingdownwardly to engagethe tree extremity with the' screen adjacent the holder as shown in Fig.4t. This bends the screen against the sash closely, while at theopposite end of the sash the screen is held in contact with the latterby the holder bent margin Q3. Each pivoted terminal l1 of the clips hasa curved cam edge 12, which clears the abutting part 4 of' thel holderwhen the clip is Vswung iipwaidly to disengage it 'from the screen 1,but to engage the part L when swung downwardly to hold the clip longi-vtudinally directed relative to the screen.

Vhen one or more lifting handles 24; are

'provided on the lower cross-bar oi the sash trame 28. the upperlongitudinal 'marginot the screen may be kept in close contact with thiscross-barby the following device. The i device is a small .met-al plate25 whose iniddle part is curved semicirciilarly at 27 and its end partspartially separated by slots to provide the springlingers 26. Thedevice' is mounted with its middle raised part 2T under and enga-gingthe lifter hook 24, the upper margin of the screen being inserted insaid slots back. ot the lingers 26 which latter thus hold the screentightly in place against' the sash cross-bar.

This type ot screen is thus readily adjusta-ble in its length to windowopenings of varying widths, so only one size ot screen need 'be carried,in stock.

sash mounted movably in said casing.`

inserted in a grooved holder 3 or 23 the flat 70 stiles cannot rot-atewhile under tension, within the groove narrower than t-he stiles width.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:V

l. In combination, a flexible screen, flat stiles connected to the endsthereof, and grooved holding devices whose ,grooves are narrowerthanrthe widths of said stiles adapted to be removably mounted on the.`jambsof a window-casing to releasably` receive and retain underlongitudinal tension the stiles interlockingly and non-rotatably Q5 andsaid screen. L'

2. In combination, a Hexible screen having. tubular ends, stilesremovably mounted'in said tubular ends, grooved platesremcvably mountedVon supporting-means to receive said tubular ends and stilesinterlockingly and non-rotatably, and resilient( pressures fingersmounted pivotallypon one of said 'plates to engage and tension saidscreen ad jacent the plate.

3. In combination, a exible screen having tubular endsg'stiles removablymou-ntedin said tubular ends, the screen being windable" at its lendsaround said "incased stiles to shorten itsv length adjustingly, andmeans mounted removably -on opposite window jainbs to .i-eleasablyfandinterlockingly i'e-` `cei've and hold said incased stiles non-rotatablywith the screen` wound thereon under lengthwise tension.
